On the other hand, in this figure, the rear cover 103 is coupled to the case 101 to cover the battery 191 to limit the detachment of the battery 191 and to protect the battery 191 from external shocks and foreign substances. are doing When the battery 191 is detachably configured to the terminal body, the rear cover 103 may be detachably coupled to the case 101 .

An accessory for protecting the appearance of the mobile terminal 100 or supporting or extending a function of the mobile terminal 100 may be added. As an example of such an accessory, there may be a cover or a pouch that covers or accommodates at least one surface of the mobile terminal 100 . The cover or pouch may be configured to extend the function of the mobile terminal 100 by interworking with the display unit 151 . As another example of the accessory, there may be a touch pen for assisting or extending a touch input to a touch screen.

Meanwhile, in the present invention, information processed in the mobile terminal may be displayed using a flexible display. Hereinafter, based on the accompanying drawings, this will be described in more detail.

2 is a conceptual diagram for explaining another example of a deformable mobile terminal 100 according to the present invention.

As illustrated, the display unit 151 may be configured to be deformable by an external force. The deformation may be at least one of bending, bending, folding, twisting, and curling of the display unit 151 . Such a deformable display unit 151 may be referred to as a 'flexible display unit'. Here, the flexible display unit 151 may include both a general flexible display, e-paper, and a combination thereof. In general, the mobile terminal 100 may include features of the mobile terminal 100 of FIGS. 1A to 1C or features similar thereto.

A general flexible display refers to a durable display that is not easily broken because it is manufactured on a thin and flexible substrate that can be bent, bent, folded, twisted or curled like paper while maintaining the characteristics of a conventional flat panel display.

In addition, electronic paper is a display technology to which characteristics of general ink are applied, and may differ from conventional flat panel displays in that it uses reflected light. Electronic paper can change information by using a twisted ball or by using electrophoresis using a capsule.

In a state in which the flexible display unit 151 is not deformed (eg, a state having an infinite radius of curvature, hereinafter referred to as a first state), the display area of the flexible display unit 151 becomes a flat surface. In a state deformed by an external force from the first state (eg, a state having a finite radius of curvature, hereinafter referred to as a second state), the display area may be a curved surface. As illustrated, the information displayed in the second state may be visual information output on the curved surface. Such visual information is implemented by independently controlling the light emission of sub-pixels arranged in a matrix form. The unit pixel means a minimum unit for realizing one color.

The flexible display unit 151 may be placed in a curved state (eg, vertically or horizontally curved) rather than a flat state in the first state. In this case, when an external force is applied to the flexible display unit 151 , the flexible display unit 151 may be deformed into a flat state (or less curved) or more curved.

Meanwhile, the flexible display unit 151 may be combined with a touch sensor to implement a flexible touch screen. When a touch is made on the flexible touch screen, the controller 180 (refer to FIG. 1A ) may perform a control corresponding to the touch input. The flexible touch screen may be configured to sense a touch input not only in the first state but also in the second state.

On the other hand, the mobile terminal 100 according to the present modified example may be provided with a deformation detecting means for detecting the deformation of the flexible display unit 151 . Such a deformation detecting means may be included in the sensing unit 140 (refer to FIG. 1A ).

The deformation detecting means may be provided in the flexible display unit 151 or the case 101 to detect information related to the deformation of the flexible display unit 151 . Here, the information related to the deformation may be a direction in which the flexible display unit 151 is deformed, a deformed degree, a deformed position, a deformed time, and an acceleration at which the deformed flexible display unit 151 is restored. In addition, the flexible display unit 151 may be various types of information detectable due to bending.

In addition, the controller 180 changes information displayed on the flexible display unit 151 based on the information related to the deformation of the flexible display unit 151 sensed by the deformation detecting means, or the mobile terminal 100. It is possible to generate a control signal to control the function of

Meanwhile, the mobile terminal 100 according to the present modification may include a case 101 accommodating the flexible display unit 151 . The case 101 may be configured to be deformable together with the flexible display unit 151 by an external force in consideration of the characteristics of the flexible display unit 151 .

In addition, a battery (not shown) included in the mobile terminal 100 may also be configured to be deformable together with the flexible display unit 151 by an external force in consideration of the characteristics of the flexible display unit 151 . In order to implement the battery, a stack and folding method in which battery cells are stacked upward may be applied.

The state transformation of the flexible display unit 151 is not limited only to an external force. For example, when the flexible display unit 151 has a first state, it may be transformed into a second state by a command of a user or an application.

3A to 3C are views illustrating a bent state of the mobile terminal 100 according to an embodiment of the present invention. That is, FIG. 3A shows that one end, particularly, the lower end of the mobile terminal 100 is bent with a constant curvature, and FIG. 3B shows that the upper end and the lower end of the mobile terminal 100 have first and second hinges 130a and 130b, respectively. ) shows bending with a constant curvature (R1, R2). At this time, the curvatures R1 and R2 at the upper end and lower end in FIG. 3B may be the same or different from each other.

3C is a view showing the bending process of FIGS. 3A and 3B. That is, it is in a flat state as in the first drawing in FIG. 3c normally, but in case of a phone call with the other party, by bending the lower end of the mobile terminal 100 as in the second drawing in FIG. 3c, it is more closely attached to the user's face (face fitting). In addition, by bending at the top and bottom of the mobile terminal 100, the whole may have a single curvature. That is, the radius of curvature (R1=R2) formed by each of the first and second hinges 130a and 130b is the same, and the radius of curvature of the mobile terminal 100 may also be the same.

In the case of playing multimedia such as video or music, as shown in the third drawing of FIG. 3C , the upper and lower ends of the mobile terminal 100 may be bent to a predetermined curvature so that the user can be immersed in the screen.

In this case, when the upper and lower ends of the mobile terminal 100 are bent to a certain curvature, there is an advantage that the mobile terminal can be mounted without a separate accessory.

In one embodiment of the present invention, the state shown in the first drawing in Fig. 3c is called a first state, the state shown in the second figure in Fig. 3c is called a second state, and the state shown in the third figure in Fig. 3c is called a third state. will be called and explained.

The flexible circuit board 151c is electrically connected to the main circuit board 181 through a hole H1 formed in the frame 102 and a hole H2 formed in the case 101 .

When the case 101 is bent from the first state to the second state, it tries to return to the first state by the restoring force, but the mobile terminal 100 is not restored to the first state by the hinge unit 130 . The second state can be maintained.

The joint units (161, 162, 163) include a first joint unit 161 and a second joint unit 162 that are disposed to be spaced apart from each other, and the first and second joint units (161, 162) are formed in one direction. The one direction may mean a longitudinal direction of the mobile terminal 100, but is not necessarily limited thereto.

The first and second joint units (161, 162) are each made of a plurality of joints (165). In addition, the third joint unit 163 is formed in a direction crossing the one direction is formed to cross the first and second joint units (161, 162). That is, the third joint unit 163 is made of a single joint, is formed along the width direction of the mobile terminal (100). The first and second joint units 161 and 162 form a part of the case 101 .

The first to third joint units (161, 162, 163) are accommodated in the case (101). The first and second joint units 161 and 162 have the same number as each other, and are formed facing each other. The plurality of joints 165 are fastened to the frame 102 , and one end forms a side appearance of the mobile terminal 100 . Both ends of the third joint unit 163 are fixed to the frame 102 , and form a side appearance of the mobile terminal 100 , like the first and second units 135 and 136 .

The third joint unit 163 is formed in the width direction of the mobile terminal 100 in the middle portion of the first and second joint units (161, 162). That is, the first and second joint units (161, 162) are bisected by the third joint unit (163), and the frame 102 on the left and right with respect to the third joint unit (163) is independently bent, The first and second joint units 161 and 162 are also bent together with the frame 102 . That is, the third joint unit 163 is a reference point that is not bent, so that the bisected portion of the first joint unit 161 and the second joint unit 162 can be bent independently. In other words, as shown in Figure 3c, the first and second joint units (161, 162) of the upper (or left) portion of the third joint unit 163 and the first and second joint units ( 161, 162) of the third joint unit 163, the lower (or right) portion of the curvature may be the same or different from each other. In this case, the entire mobile terminal 100 may form a single curvature as described above.

8 is a perspective view from the front of the joint unit (161, 162, 163) and the hinge unit 130 related to an embodiment of the present invention are fastened, the first and first on the upper side of the third joint unit 163 The two joint units (161, 162) are called a first part (161'), and the first and second joint units (161, 162) on the lower side of the third joint unit 163 can be called a second part (162'). have. The first and second portions 161 ′ and 162 ′ are bent at the same curvature as that of first and second hinges 130a and 130b to be described later, respectively.

12 is a combined perspective view of the first hinge part 130a according to an embodiment of the present invention, and FIG. 15 is an exploded perspective view of the hinge part 130 according to an embodiment of the present invention. 8, 12 and 15 , the hinge part 130 includes first and second hinges 130a and 130b, and one of the first and second hinges 130a and 130b is formed. The ends are respectively fastened to the third joint unit 163 , and the other end is respectively fastened to the ends of the case 101 .

The first and second hinges 130a and 130b have a symmetrical arrangement structure. The first hinge 130a is provided between the first portion 161' of the first and second joint units 161 and 162 described above and is bent to the same curvature as the first portion 161', and the second The hinge 130b is provided between the second part 162' of the first and second joint units 161 and 162 and is bent with the same curvature as the second part 162'.

Since the first and second hinges 130a and 130b have the same structure, hereinafter, the first hinge 130a will be mainly described, and the second hinge 130b will be replaced with the description of the first hinge 130a. decide to do

The first hinge 130a includes a corrugated plate 132 having a concave-convex shape, and a base portion 131 that covers one surface of the corrugated plate 132 and surrounds the side surface of the corrugated plate 132 . ), and a cover portion 133 covering the other surface of the corrugated plate 132, and a high that is provided in the space between the base portion 131 and the cover portion 133 to maintain the fixed state of the case 101 Government 134 is included. The fixing part 134 is formed on one side of the corrugated plate 132 . The corrugated plate 132 has a concave-convex shape in which a convex portion and a concave portion are continuously formed, and the convex portion and the concave portion may be formed to form a right angle or may be formed to form a parabolic shape like a wave or wave. 15 illustrates that the concave-convex shape forms a right angle.

Both ends of the corrugated plate 132 , the base part 131 and the cover part 133 are fixed. More specifically, one end of the corrugated plate 132 , the base portion 131 and the cover portion 133 is fixed to the third joint unit 163 , and the other end is fixed to the case 101 . That is, as shown in FIG. 15 , one end of the corrugated plate 132 , the base part 131 and the cover part 133 is fixed by a fastening member 139a. In addition, it may be fixed by the dowel pin (139d), and a more accurate assembly position can be controlled by the dowel pin (139d). In other words, the corrugated plate 132, the base part 131, and the cover part 133 can be fixed by the fixing member 139a, but shaking may occur due to a slight assembly tolerance, etc., more precisely In one embodiment of the present invention for assembly, a dowel pin (139d) was used.

In addition, the fixing part 134 includes a first unit 135 fastened to the cover part 133 and having a first screw thread 135b formed thereon, and a second screw thread 136b facing the first screw thread 135b. ) is formed to face the first unit 135 and includes a second unit 136 movable in the opposite direction to the first unit 135 . In this case, the first and second screw threads 135b and 136b may further include an elastic member 137 for contacting the second unit 136 toward the first unit 135 so that the first and second threads 135b and 136b are in close contact with each other. The movement of the first and second units 135 and 136 is a forcible positional movement due to a difference in elongation amount. This will be described later.

The first unit 135 , the second unit 136 , and the elastic member 137 are accommodated in the housing 138 . The housing 138 is adapted to support the elastic member 137 . The first unit 135 is disposed at the end of the corrugated plate 132 and is fastened to the cover part 133 . In addition, a first protrusion 138a is formed on one surface of the housing 138, and a second protrusion 136a is formed on a surface facing the first protrusion 138a of the second unit 136, The elastic member 137 is fixed by the first and second protrusions 138a and 136a. In addition, the second unit 136 is fixed by the second protrusion 136a , and the housing 138 is fixed to the base part 131 . Accordingly, the second unit 136 is fixed to the base portion 131 .

Referring to FIG. 15 , joint portions 131b and 138b are formed in the housing 138 and the base portion 131 , respectively. Hereinafter, the bonding portion 131b formed on the base portion 131 will be referred to as a first bonding portion 131b, and the bonding portion 138b formed on the housing 138 will be referred to as a second bonding portion 138b. The first bonding portion 131b is formed to be stepped with the main surface of the base portion 131 , and the second bonding portion 138b is formed to be stepped with the main surface of the housing 138 . Fastening holes 131c and 138c are formed in the first and second joining portions 131b and 138b and joined by a fastening member 139c. In addition, a fastening hole 135a is formed in the first unit 135 , and a fastening hole 133a is formed in the cover part 133 , and a fastening member 139b is formed through the fastening holes 135a and 133a. ), the first unit 135 is fastened to the cover part 133 .

The first and second bonding portions 131b and 138b are to be fastened to the protruding members 106a and 106b shown in FIGS. 7A to 7C . That is, as shown in FIG. 7A , there is a height difference between the protrusion members 106a and 106b protruding from the rear surface of the frame 102 and the rear surface of the frame 102 , the hinge portion 130, more specifically As a result, the thickness of the base part 131 has a thickness corresponding to the height difference. That is, referring to FIG. 13A , the base part 131 is provided with a plurality of nodes 131a divided into a plurality of parts while enclosing both sides of the corrugated plate 132 , and the nodes 131a are connected to each other. It is formed to be spaced apart by a predetermined interval (D).

Accordingly, the hinge part 130, more specifically, the base part 131 can be easily bent without applying a large force when bending. If both sides of the base part 131 are formed integrally without dividing, the base part 131 will not be easily bent.

13A to 14B are views for explaining a process in which the hinge part 130 is bent according to an embodiment of the present invention, and only the first hinge 130a or the second hinge 130b of the hinge part 130 is shown in FIGS. it will be shown That is, only half of the hinge portion 130 is illustrated.

14A and 14B are conceptual diagrams for explaining the bending principle of the mobile terminal 100 according to an embodiment of the present invention. 14A and 14B are views that do not coincide with the fixing part 134 shown in FIG. 15, which is conceptually illustrated for convenience of description. That is, in FIG. 15 , the first and second screw threads 135b and 136b are not formed on the base portion 131 and the cover portion 133 , respectively, and only the first and second units 135 and 136 are fixed thereto. That is, the first unit 135 is fastened to the cover part 133 , and the second unit 136 is fixed to the base part 131 through the housing 138 . As a result, it can be understood that the first screw thread 135b is formed on the cover portion 133 , and the second screw thread 136b is formed on the base portion 131 . 14A and 14B show this.

13A to 14B , FIGS. 13A and 14A show a first state, and FIGS. 13B and 14B show a second state. When the mobile terminal 100 is bent by the user in the first state, since the hinge part 130 has a certain thickness, the elongation amount of the upper surface and the lower surface of the hinge part 130 is different. That is, the elongation amount of the base part 131 and the cover part 133 in FIGS. 13A and 14A is different. More specifically, compression occurs in the base portion 131 , and tension occurs in the cover portion 133 . In other words, the amount of stretching in the cover portion 133 is greater than in the base portion 131 .

At this time, the corrugated plate 132 becomes a neutral axis that is not compressed or stretched. The neutral axis refers to an imaginary axis that is neither compressed nor stretched during bending. Accordingly, compression occurs on the inside of the neutral axis and tension occurs on the outside of the neutral axis, so that the elongation amount at the inside and outside of the member having a thickness is different.

In the first state, the first and second threads 135b and 136b are engaged as shown in FIG. 14A , but when the hinge part 130 is bent by the user, the cover part 133 rather than the base part 131 is engaged. The amount of elongation becomes large, so that the meshing threads in the first and second threads 135b and 136b move as shown in FIG. 14b. In addition, the first and second threads 135b and 136b are similar to those in gear coupling, so that their state is maintained unless a force of a certain magnitude is applied. Accordingly, the mobile terminal 100 maintains the second state. In this case, the curvature of the mobile terminal 100 may be adjusted according to the number of the screw threads 135b and 136b. That is, as the number of the screw threads 135b and 136b increases, the movement period between the base part 131 and the cover part 133 can be further increased, so that the radius of curvature of the mobile terminal 100 can be made smaller.

The same is true for the third state. That is, the frame 102 bent by the first and second hinges 130a and 130b can maintain a bent state.

5 is a perspective view of the mobile terminal 100 according to an embodiment of the present invention, in a state in which the display unit 151 is removed. Referring to FIG. 5 , the frame 102 is accommodated in the case 101 . In an embodiment of the present invention, the mobile terminal 100 is bent downward to be convex. For this, the frame 102 needs to be formed smaller than the case 101 . That is, since the radius of curvature of the inner component is greater than the radius of curvature of the outer component, the frame 102 moves on the case 101 . In order to secure a moving space of the frame 102, the case 101 is provided with a region in which the frame 102 moves when bending. That is, areas A1 and A2 spaced apart from the frame 102 are formed on the upper and lower sides of the case 101 as shown in FIG. 5 .

However, one embodiment of the present invention is not limited thereto, and although not specifically illustrated, the frame 102 may be formed on the case 101 smaller than the size of the frame 102 . In this case, the frame 102 may form a side appearance, the case 101 is provided therein, and an empty space should be formed between the case 101 and the frame 102 . This may be similar to an inverted shape of the case 101 in which the frame 102 is accommodated in FIG. 5 .

On the other hand, Figure 6 is a cross-sectional view taken along the AA of Figure 5, Figures 7a to 7d are views for explaining the fastening process of the joint unit and the hinge unit 130 related to an embodiment of the present invention, Figure 8 is It is a perspective view viewed from the front in a state in which the joint unit and the hinge unit 130 are fastened.

Referring to FIG. 7A , first and second guide rails 104a and 104b formed in one direction (eg, the longitudinal direction of the mobile terminal 100 ) are formed on the rear surface of the frame 102 . The guide rails 104a and 104b perform a function of a rail on which the first and second joint units 161 and 162 can move.

That is, the joints 165 of the first joint unit 161 are moved and fixed to the first guide rail 104a, and the joints of the second joint unit 162 to the second guide rail 104b. The poles 165 are moved and fixed. In this way, the joints 165 of the first and second joint units 161 and 162 may move on the first and second guide rails 104a and 104b.

To this end, the first and second guide rails 104a and 104b protrude from the rear surface of the frame 102, respectively, and the first guide 105a and the first guide ( 105a) and a second guide 105b that is formed to be spaced apart and bent along a direction crossing the one direction. The first and second guides 105a and 105b may be formed to protrude from the frame 102 or may be fastened to the frame 102 as separate parts. A boss 125 is formed on the rear surface of the frame 102 so that the third joint unit 163 can be attached thereto.

Figure 9 is a view showing a joint fastened to the frame related to an embodiment of the present invention, Figure 10 is an example of the joint of the first joint unit or the second joint unit according to an embodiment of the present invention, Figure 11 is a cross-sectional view taken along BB of FIG. 9 .

Referring to FIGS. 9 to 11 together with FIGS. 7A to 7D , each of the first and second joint units 161 and 162 includes a plurality of joints 165 , wherein each of the joints 165 is It can move without being separated by the first and second guides 105a and 105b. To this end, the first and second guides 105a and 105b are provided with first and second protrusions 165a and 165b. The first and second protrusions 165a and 165b may be formed toward the inside or outside of the mobile terminal 100 . The first and second guides 105a and 105b may have an undercut or C-cut shape due to the first and second protrusions 165a and 165b.

The first and second guides 105a and 105b do not have to be identical to each other, and it is sufficient if they have a structure in which the first and second protrusions 165a and 165b do not separate. For example, the first guide 105a or the second guide 105b has an approximately 'L' shape formed from the frame 102 . Accordingly, the frame 102 and the first and second guides 105a and 105b may form an approximately 'C' shape.

In one embodiment of the present invention, the first protrusion 165a moves on the first guide 105a, the second protrusion 165b moves on the second guide 105b, and the first protrusion 165a and the second protrusion 165a move on the second guide 105b. One guide 105a has a structure corresponding to each other. This also applies to the second protrusion 165b and the second guide 105b.

Accordingly, when the shape of the first protrusion 165a is changed, the shape of the first guide 105a must also change, and this is also the case with the second protrusion 165b and the second guide 105b. In addition, one end of any one of the first and second protrusions 165a and 165b is formed along the one direction to move only in the one direction and to limit movement in the opposite direction to the one direction. A limiting portion 165c is formed. Hereinafter, it will be described that the first and second protrusions 165a and 165b are formed toward the outside of the mobile terminal 100 in the first guide 105a and the second guide 105b as shown in FIG. 6 . .

As shown in FIG. 10 , the movement limiter 165c is exemplified as being formed on the first protrusion 165a. However, the positions of the first protrusion 165a and the second protrusion 165b may be changed, respectively, and in this case, the structures of the first and second guides 105a and 105b should also be changed.

The movement limiting part 165c is formed to extend from the first protrusion 165a and is bent to be formed along the one direction. And, the distal end of the movement limiting portion 165c is formed at the end of the inclined portion 1651 and the inclined portion 1651 is formed to be inclined toward the one direction gradually away from the first protrusion 165a, and and a locking part 1652 formed in a direction crossing the one direction. This is to allow the joint to move in only one direction. That is, as shown in FIGS. 7C and 7D , the joint 165 is inserted and moved from the upper end or lower end of the first and second guide rails 104a and 104b. For example, the first joint is fitted from the upper end of the first guide rail 104a formed in the frame 102 to move to the third joint unit 163, and the second joint is the first guide rail 104a. It is fitted from the top and moves to the first joint. At this time, if the joints 165 fitted in the frame 102 move in the opposite direction, they may be separated from the first guide rail 104a. In order to prevent this, the locking part 1652 is formed in the movement limiting part 165c.

Looking at the process in which the joint 165 moves along the first guide rail 104a, since the movement limiting part 165c is formed to be spaced apart from the first protrusion 165a, the inclined part 1651 is the second 1 It moves while in contact with the inner surface of the guide 105a. In this case, the movement limiter 165c is bent toward the first protrusion 105a. The first and second guides 105a and 105b are formed in plurality, respectively, and are formed to be spaced apart from each other, so that the movement limiting portion 165c of the joint 165 faces each other first and second guides 105a and 105b. After passing through, it returns to its original state. That is, after the joint 165 passes through the pair of first and second guides 105a and 105b, it becomes parallel to the first protrusion 165a. The joint 165 fastened to the frame 102 repeats this process while passing through several pairs of the first and second guides 105a and 105b.

10 shows an example of the joint 165 of the first joint unit 161 or the second joint unit 162 according to an embodiment of the present invention, the joint 165 is a first protrusion on one side A 165a is formed, and a second protrusion 165b is formed on the other side opposite to the first protrusion 165a. Since the first and second guides 105a and 105b have a 'C' shape together with the frame 102 , the first and second protrusions 165a and 165b form the first and second guides 105a and 105b. It is inserted into and does not escape.

The first to third states are implemented by the mobile terminal 100 as described above, and by using this, in an embodiment of the present invention, power on/off and video on/off functions can be performed, and furthermore, a specific application can be executed or stopped. That is, when switching from the first state to the second state or the third state, the power may be turned on or a video related menu may be turned on, and when the first state is switched back to the first state, the power may be turned off or the video may be turned off. In particular, when a voice call signal is received, a call can be made by switching to the second state, and when the call is terminated, the call can be terminated by restoring the first state.

The same is true for video playback. That is, when the video selected in the first state is to be played, the video is played when the video is switched to the third state, and when the video is restored to the first state, the video can be ended. However, the present invention is not limited thereto, and a function that can be processed by a binary number (0 or 1) is sufficient, such as switching between the first state and the second or third state.

As such, in an embodiment of the present invention, a control command may be input by switching from the first state to the second or third state, or by switching from the second or third state to the first state.

The present invention described above can be implemented as computer-readable code on a medium in which a program is recorded. The computer-readable medium includes all types of recording devices in which data readable by a computer system is stored. Examples of computer-readable media include Hard Disk Drive (HDD), Solid State Disk (SSD), Silicon Disk Drive (SDD), ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, etc. There is also a carrier wave (eg, transmission over the Internet) that is implemented in the form of. In addition, the computer may include the control unit 180 of the terminal. Accordingly, the above detailed description should not be construed as restrictive in all respects but as exemplary. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the present invention are included in the scope of the present invention.
